We are pleased to announce the release of phpBB 3.1.9 "Bertie's virtual reality beach". This version is a maintenance release of the 3.1.x branch which fixes various smaller bugs including improper column defaults for new table columns in MSSQL, issues with the updater while using caches that are not file based, as well as duplicate emails being sent by the email queue due to opcache, and attached images not being displayed in the expected order when adding them inline. It also adds support for X-Forwarded headers for upgrading non-SSL connections to SSL and allows extension authors to disable sending headers on Extension pages served via app.php.
